The Graduate Institute of Mind, Brain, and Consciousness at Taipei Medical University is proud to announce that four members, Risa Dwi Ratnasari, Elham Dabiri
, Nguyen Trong Nguyen and Vuong Hung Truong successfully participated in the 2025 Summer School on Non-Stationary Signal Processing Analysis. This program was organized by Academia Sinica’s Department of Mathematics and held at National Taiwan University (NTU).
Program Overview
The summer school focused on the theory and practical applications of non-stationary signal processing, with special emphasis on biomedical signals. Topics included:
Short-Time Fourier Transform (STFT)
Empirical Mode Decomposition (EMD)
Time-Frequency Ridge Extraction
Manifold Learning
This summer, four students from the Graduate Institute of Mind, Brain, and Consciousness at Taipei Medical University—Risa Dwi Ratnasari, Elham, Ben, and Vuong—were excited to join the “2025 Summer School on Non-Stationary Signal Processing Analysis,” hosted by Academia Sinica’s Institute of Mathematics and held at National Taiwan University. It was an honor to be selected from a pool of talented applicants across mathematics, physics, data science, engineering, neuroscience, and medicine, both from Taiwan and abroad!
Interdisciplinary Learning and Hands-on Experience
The program focused on non-stationary signal processing, combining in-depth theory with practical applications, especially in biomedical contexts. Participants explored topics such as STFT, EMD, time-frequency ridge extraction, manifold learning, adaptive and nonlinear filtering, and the use of PPG (photoplethysmography) for sleep signal analysis. Renowned professors from Duke University, the University of Minnesota, the University of Haifa, and other institutions led a dynamic mix of lectures and hands-on MATLAB workshops.
Diverse Activities and Academic Exchange
Each week, students attended four days of intensive lectures and practical training. Highlights included trying out sleep analysis devices developed by Prof. Hau-Tieng Wu’s team, as well as field visits to the Sleep Medicine Center and Cardiology Unit at Taipei Veterans General Hospital for a real-world perspective on biomedical signal processing. The program concluded with panel discussions and case studies, encouraging in-depth interdisciplinary exchange.
A special mention goes to Vuong, who was invited to serve as a teaching assistant, supporting discussions and helping classmates—a unique and valuable experience!
Achievements and Reflections
At the end of the three-week program, all participants received certificates of completion. This summer school not only helped our students gain advanced knowledge and skills in signal processing but also fostered new connections with peers and scholars from different fields, further strengthening TMU’s commitment to interdisciplinary research and international collaboration.
Congratulations once again to Risa Dwi Ratnasari, Elham Dabiri, Nguyen Trong Nguyen and Vuong Hung Truong! We look forward to seeing how you will apply what you’ve learned in your future research journeys.
